Distinguished by its 37 mm ultra-slim case and stylish tear-drop lugs, this exceptional timepiece is certainly one of the most elegant minute repeating perpetual calendar wristwatches of the modern era. Superb and highly attractive with a resonant and clear repeating chime, it is part of Patrimony Collection. Treasured in an important private collection for several years, it is preserved and presented in excellent condition.

The Vacheron Constantin Patrimony Minute Repeater Perpetual Calendar is a most desirable trophy in today’s collectors market and does not fail to impress on every level. Due to the extreme cost and complexity of minute repeating wristwatch production, only an exceedingly small number of such horological masterpieces are ever made. As well as being a minute repeater and a perpetual calendar, Vacheron Constantin surpassed even this technical challenge by making the caliber ultra-thin, thus combining three complications requiring special manufacturing know-how and tremendous skills.

The present reference 30020, is fitted with the caliber 1755 movement, introduced in 1992, which measures only 3.28 millimeters in depth, the thinnest minute repeater ever made by Vacheron Constantin. The minute repeating caliber, caliber 1755, was only made in 200 examples. The majority was cased in reference 30010 and reference 30030 (with skeletonized dial). 77 examples, however, were upgraded with the perpetual calendar / moonphases module, and nearly all of them were cased in the present reference 30020.
